Abstract

Character, relations of age and genesis of flysch, olisthostromes and sliding nappes in the Harz mountains as well as their connection to the Orogenesis are being investigated. This order of phenomenas shows states of gradation of tectonic activity. Flysch and olisthostromes result from submarine pre- or early orogene turbidity currents and mud flows; and the sliding nappes (= sedimentary nappes) having been moved forward by many kilometres came out by previously moved uplifts in SE. All ± synsedimentary sliding phenomenas became impressed by the following highly orogenic compression ± autochthonously. In the Harz mountains synsedimentary sliding nappes therefore exist, but also orogenic autochthony. The considerable sedimentary sliding phenomenas have, besides strong primary sideways differences in facies which led to disharmonic deformation (changing facies tectonics), much importance for the building and structure of the Harz variscicum.
